I am trying to build a stand alone Spring based Java application.
I am using Maven assembly plugin to build the JAR with dependencies. The strcture of the JAR ends up looking like this (Just a subset):
com
META-INF
org
properties
- taskexecutor.properties
spring
- properties.xml
.
.
.
Manifest looks like this:
Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Created-By: Apache Maven
Built-By: authorname
Build-Jdk: 1.6.0_30
Main-Class: com.company.utilities.task.TaskLauncher
When the application runs the property placeholder should be configured by including the properties.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd">
<context:property-placeholder location="classpath:/properties/taskExecutor.properties"/>
</beans>
It runs fine in Eclipse, but when I run the JAR I get this error:
Exception in thread "main" org.springframework.beans.factory.BeanInitializationException: Could not load properties; nested exception is java.io.FileN
otFoundException: class path resource [properties/taskExecutor.properties] cannot be opened because it does not exist

Any ideas?
将taskExecutor.properties移至root并尝试
<context:property-placeholder location="taskExecutor.properties"/>
It appears running through the command line is case sensitive but Eclipse is not when loading these resources.
Renaming taskexecutor.properties
to taskExecutor.properties
fixed the issue. Oops. Hopefully this helps someone equally as stupid as me in the future ;-)
